Patent

CA 2028588

The disclosure describes a catalyst composition for use in a Fischer-Tropsch process, in which the composition comprises activated carbon. It has been found that activated carbon of which at least 90 percent of the particles is smaller than 45 micron or of which at least 90 percent of the particles fall within the range of 850 micron to 1200 micron yields particularly good results. The disclosure also describes a method of manufacturing an iron-based catalyst composition for use in a Fischer-Tropsch process, in which activated carbon is added to any of the catalyst pre ursors, at any stage prior to the extrusion stage.

L'invention décrit une composition catalytique renfermant du charbon actif pour un procédé Fischer-Tropsch. On a observé que le charbon actif, dont au moins 90 % des particules mesurent moins de 45 microns, ou dont au moins 90 % des particules ont une taille se situant entre 850 et 1200 microns, donne des résultats particulièrement intéressants. On décrit également une méthode de production d'une composition catalytique à base de fer pour procédé Fischer-Tropsch, dans laquelle le charbon actif est ajouté à n'importe lequel des précurseurs de catalyseur et à n'importe quelle étape avant l'étape d'extrusion.
